A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Lazulite is a relatively rare magnesium iron aluminum phosphate that typically appears in rich azure to deep blue colors, sometimes with greenish or grayish tones. Crystals can be transparent to translucent but are usually small and often included. With Mohs hardness around 5.5–6 and good cleavage, it is best suited to collector gems and cabochons rather than heavy-wear jewelry.
